It is a big deal, if true. Personally, the reason i want ps5 to play ps4 games is because i have 30 ps4 games i haven't played yet and another 30-40 in my wishlist.
I don't want to buy another ps4 to finish them, just like i did with ps3 on 2015.And i take good care of my consoles. Ps1 is 23 years old and still kicking.Ps2 is 19, SNES is 26, GB is 27.
The latest generation consoles are prone to malfunctions, no matter what you do

On NA store it asks for credit card if you try to get the 1 month package, even if you have 10 dollars in wallet
That doesn't happen with 3 months though. You can buy that just with 25 dollars in psn wallet and no need for credit
I don't know about the 12 months

Check the maps, it numbers where they are

Yes they are random.

If you check each Board (Royal,Keyboard etc) it shows the panel where it may appear. So aim for that one at the beginning and if it's not there, quit and retry.
Also, play don't attempt that in the arena, only on the world map
